论文摘要
来自原子系统的共振荧光由单光光峰组成，该光谱峰会演变成Mollow Triplet，以获得强烈的激发场。来自三胞胎不同峰的光子显示出明显的光子相关性，使荧光成为量子信息目的的有用光源。我们表征了单个光学捕获的$^{87} $ rb原子的荧光，该$^{87} $ rb原子在不同的功率水平上引起了共识。二阶相关测量结果揭示了荧光的单个光子性质，同时与强烈激发原子的Rabi振荡同时揭示了荧光。当原子暴露于异子场时，来自荧光光谱的两个侧带的光子之间的相关性不对称性进一步表明，来自不同边带的发射光子的首选时间顺序。
Resonance fluorescence from atomic systems consists of a single spectral peak that evolves into a Mollow triplet for a strong excitation field. Photons from different peaks of the triplet show distinct photon correlation that make the fluorescence a useful light source for quantum information purpose. We characterize the fluorescence of a single optically trapped $^{87}$Rb atom that is excited resonantly at different power levels. Second-order correlation measurements reveal the single photon nature of the fluorescence concurrently with Rabi oscillations of a strongly excited atom. The asymmetry in correlations between photons from two sidebands of the fluorescence spectrum when the atom is exposed to an off-resonant field further indicates that there is a preferred time-ordering of the emitted photons from different sidebands.
